HENRI MAURICE PIPLU, OF PARIS, FRANCE.

CARBURETER.

Specification of Letters Patent.

Patented Nov. e, 1910.

Application filed March 29, 1909. Serial No. 486,558.

To all whom 'it may concern:

Be it known that I, HENRI MAURICE PIPLU, a citizen of the FrenchRepublic, and resident of Paris, France, have invented certain new anduseful Improvements in Carbureters, of which the following is aspecication.

This invention relates to improvements in carbureters of that type inwhich carbureted air is produced in accordance with and controlled byconsumption thereof.

One of the features of my invention consists in providing a regulatingdevice for the oil through which the same flows by gravity into thecarbureter and which is controlled by mechanism for supplying the air tothe carbureter so as to supply oil thereto in predetermined quantitiesproportioned to the supply of air and wherein the supply of air and oilare both controlled by consumption of the carbureted air.

The invention will be more fully described in connection with theaccompanying draw ings and will be more particularly pointed out in andby the appended claims.

In the drawings Figure 1 is a View partly in section and partly inelevation showing the controlling device for the oil in connection withone form of carbureter and also showing a portion of the air supplying,`means operatively connected with the oil controlling device to operatethe same. Fig. 2 is a vertical sectional view on line 2 2 of Fig. l.Fig. 3 is a sectional View of the modified form of carbureter. Fig. 4 isa view partly in elevation and partly in section of a complete apparatusembodying my invention. Fig. 5 is a vertical sectional view of Fig. 4with the oil controlling device and carbureter omitted. Fig. 6 is asectional view of the device shown in Fig. 5.

Like characters of reference designate similar parts throughout thedifferent tigures of the drawings.

First referring to Figs. 4, 5, and 6, the mechanism for supplying air isshown as consisting of a casing 38 adapted to contain a body of liquid39 and provided with a closable opening 40 through which the casing maybe filled. An air outlet 41 is provided for said casing and is connectedby a pipe 23 with the carbureters 33. Within the casing 38 a shaft 42 isprovided, which eX- tends through a suitable stuling boX 43, and onwhich shaft a drum or rotor 44 is mount ed. This drum or rotor, and theparts with which it is associated may conveniently be termed a pump, andthe rotor is provided with a plurality of partitions 45 forming airbuckets. At one end of -the rotor a chamber 46 is provided into which anair inlet 47 projects. Said air inlet may, if desired, be provided witha non-return valve not shown, and also a vertical extension 48,extending above the level of the liquid 39. When the drum or rotor 44 isrotated airis drawn in through 48 in the direction of the arrows and isforced outwardly into the casing above the level of the liquid at 49 andis discharged through pipe 23 into the carbureter 33.

A convenient means for operating the rotor 44 may consist of a train ofgears 50 connecting the shaft 42 with a windlass or rope drum 51 aboutwhich one end of a rope 52 is trained. As shown said rope 52 extendsover a pulley 53 and laterally over a second pulley 54 and downwardlyover an idler 55 and upwardly therefrom where it is fixed to a ring 56.A suitable weight 57 is suspend'- ed from the idler and serves toactuate the drum 51. At one end of the drum 5l a gear 58 is mounted andmeshes with a gear 59 having a shaft 60 to which a wrench or likeimplement, not shown, may be applied to wind the rope 52 about the drum51 and raise the weight 57 to a starting position. A suitable pawl andratchet device 61 may be interposed in the gearing 50 so that when saidrope is wound up the rotor 44 will not be actuated.

The carbureter 33 may consist of a casing provided with suitablepartitions or diaphragms 34 affording a circuitous path for the air inits passage therethrough and as shown said carbureter has an inlet atthe connection of pipe 23 therewith and an outlet through pipe 35. Pipe35 forms the consumption or supply pipe leading to the jet or otherpoints of consumption not shown. Reference will next be made to t-he oilcontrolling device whereby oil is admitted to 7 interposed between saidcylinders 5 and 6V and provided with adjustable means therein forcontrolling admission from cylinder 5 to cylinder 6. As shown cylinder 5is connected with a source of supply of oil 62 by means of pipe 15 andthe arrangement is such that the supply is fed by gravity. In order toexclude air from the cylinder or chamber 5 one end thereof is sealed bya diaphragm 10 which is interposed between a seat formed on saidcylinder and a ring 11 conveniently forming a part of the valve stemguide or frame 12. The chamber 5 is provided with an outlet 5,preferably at its bottom, and the outlet is flared at 52 to form a seatfor a valve 8. The valve 8 is provided with a valve stem 9 which extendsupwardly through the diaphragm 10 and the latter may be secured theretoin any desirable manner such as by the nuts shown. It will be seen thatby this arrangement movement Vof the valve 8 can be effected and thechamber 5 will always be closed by the diaphragm 10. The valve stem 9pro-jects upwardly to a bore 14 in t-he frame 12 and is guided by a cap13 secured to the top of the frame 12. The bore 14 is preferablyenlarged with respect to the stem 9 so as to provide fora spring whichis interposed between the cap 13 and the nuts heretofore referred to.The spring serves to normally seat the valve 8 and close the outlet 5.An arm 31 on the frame 12 forms a pivotal bearing for an operating lever3 which is connected with the valve stem 9 and is operated in a mannerwhich4 will hereinafter be more fully described. The chamber 5 deliversto said second or intermediate cylinder or chamber 7 having a piston 25provided with a' threaded stem 26 for adjusting the capacity of saidchamber. rI`he stem 26 is grooved longitudinally to receive a set screw30 to prevent rotation of the stem 26 and piston 25. Anut 27 hasthreaded connection with the stem 26 and is rotatively mounted in thecylinder 7 as shown and is held in place therein by a cap 7 A hand wheel29 is fixed on the nut 27 by a screw 28 and when the hand wheel 29 isturned longitudinally adjusting movement is imparted to the piston 25.

The outlet or delivery casing or cylinder 6 is provided withran inlet 6having a flared seat for receiving the valve 16. The valve 16 isprovided with a valve stem 17 and the casing or chamber 6 is closed atits outer end by a diaphragm 18. VIhe diaphragm 18 is is interposedbetween the cap 21 and one of the nuts hereinbefore described tonormally hold the valve 16 in a closed or seated position. An arm isformed on the frame 22 and a lever 4 is pivoted to said arm' and isconnected with the valve stem 17 for operating the same as willhereinafter be more fully set forth. The outlet or delivery casing 6 isconnected with the carbureter 33 by a valve connection 24 to deliver theoil to the upper portion of the carbureter and permit it to Howdownwardly in a tortuous path and intermingle with the upwardly flowingcurrents of air.

In the specific construction shown the oil controlling device is drivenfrom the air supplying mechanism or pump by providing on the shaft 42 adisk 1, having a plurality of pins or equivalent parts 3 spaced at equaldistances apart from each other on said disk'. The levers 3 and 4 are sodisposed as to bring their free ends into the path of movement of saidpins 2 and the arrangement is such that the levers 3 and 4 will besequentially actuated first to open valve 8 and sebsequently open valve16` it being clear from the foregoing description that the springs closethe v valve immediately after the pins 2 pass from engagement therewith.

It will be seen fromrthe foregoing that the oil has flowed by gravityfrom the source of supply 62 until it reaches the carbureter 33 and bythis arrangement I thereby avoid the provision of pumps and the like forad-` vancing the oil thro-ugh its course.

It will be further noted that in operation oil is only admitted to thecarbureter 33 when consumption of the carbureted air is taking place andthat the admission of oil is such that the quantities admitted will"always be completely taken up by the in limit the passage of oil fromthe intake chamber 5 to the delivery chamber 6 in proportion accordingto the requirements of conditions under which the apparatus isoperating. The provision and operation of the inlet and outlet valves 8and 16 provides j for regulating the passage of oil, and mecha; 65

` nism for supplying air to said carburetor and operatively connectedwith said valves.

an effective intermittent speed and insures an economical utilization ofthe o1l and the closing of the chambers 5 and 6 amply protects the oiluntil it has reached the carbureter.

In the modified construction shown in Fig.

3 the partitions 37 are spirally formed about g a body 36 and extendfrom the intake 23 to L the outlet 35.
